If you encounter an error such as the one below during compilation for lammps such as written in Compiling LAMMPS-15Jun20 with GNU 6 and OpenMPI 3
../compute_voronoi_atom.h:24:21: fatal error: voro++.hh: No such file or directory
This is due to one of the a header file not found at /usr/local/lammps-29Oct20/src/compute_voronoi_atom.cpp. To resolve the issue, do take a look at Line 23 or 24 and edit to the path where you place voro++.hh
/* #include <voro++.hh> */ #include "/usr/local/lammps-29Oct20/lib/voronoi/voro++-0.4.6/src/voro++.hh"
